Sink is an "exe" who doesn't fall under the typical standards an average exe comes down to. He's not corrupted or possessed by some demon. He's simply just a Sonic who got caught up in a series of unfortunate circumstances. Battered and bruised, got himself caught inside the chains of an underwater mine, trapped with no air in sight. He drowned and sunk to the bottom of the Labyrinth Zone. Due to his sheer will power, much to his dismay, he is able to somehow still 'survive'. He's essentially like a zombified sonic, trapped inside a never ending state of pain, suffering, and loneliness. He doesn't know how long he's been trapped down there, endlessly waiting for SOMETHING that can save him from his agony. Days, weeks, years, decades. All he can do is wait in pain...
